RAILWAY-ENGINE-SIGNALING DEVICE.

Specification of Letters Patent.

Patented March 13. 1906.

Application filed April 13,1905- -Serial No. 255,378.

To all whom it may concern:

Be it known that I, WILLIAM S. FILLEY, a citizen of the United States,residin at T0- ledo, in the county of Lucas and tate of Ohio, haveinvented a new and useful Improvement in a Railway-Engine-SignalingDevice, of which the following is a specification.

This invention relates to an audible signalalarm device adapted to beplaced in an engine-cab and to sound an alarm when a predetermined pointupon the road has been reached and to automatically shut off the steamand stop the engine if the engineer fails to respond to the signal.

A further object is to provide a record of the response of the engineerto the said signal, said recording showing the point on the road wheresuch response was given. Should the engineer pay no attention to thesignal, the train is automatically stopped. Should he heed the signaland take proper action to prevent said automatic stoppage, a record willbe made of that fact, so that the engineer cannot disregard the signaland subsequently plead that a signal was not given or received by him. v

A further object is to actuate the device from an axle of the engine andto provide a pointer movable upon a scale or chart whereby the exactposition of the engine at any time may be known by examining the chart.

The invention consists of a fixed chart, a movable chart, said chartbeing actuated by suitable gearing connecting it with an axle of theengine, a stirrup or hanger traveling with the movable chart, suitablevalve-actuating blades pivoted adjacent one end and held in a horizontalposition by the hanger, and a pointer carried by the movable chart andadapted to travel on the fixed chart.

The invention also consists of means for sounding an alarm on the fallof one of the blades, of opening an emergency-valve on the subsequentfall of the second blade, and means whereby the engineer can lock thesecond blade against falling and reset the first.

The invention also consists in the novel features of construction andcombination of parts hereinafter described, pointed out in the claims,and shown in the accompanying drawings, in which- Figure 1 is a faceelevation of the complete device as carried within an engine-cab. Fig. 2is a plan view of the parts shown in Fig. 1.

Fig. 13 is a section on the line 13 13 ofFig. 1. v Fig. 14 is a detail end view of a hanger. Fig. 15 is a detailsectional view showing in elevation the pencil for recording fall of thesignal-blade and the valve for actuating the pencil.

In the drawings, Arepresents a suitable casing adapted to be placed inan engine-cab and closed in front toward its rear end and open adjacentthe forward end, the latter being that toward the engineer and the endat which the device is properly set and otherwise manipulated. Throughthe casing extends a shaft A, which at one end carries a gear-wheel Ameshing with a beveled gearwheel A carried at the upper end of a shaft AThe shaft A is driven, preferably, from an axle of the forward truck inany desired manner, the only essential point being that there should beno change of speed between the truck and shaft A by any variable form ofgearing and that the speed of the gear A must be in a known proportionto the speed of rotation of the axle and the diameter of the wheels ofthe said axle. At the opposite end of the shaft, termed the forward end,is a gear-wheel A A rod B is journaled in the casing A parallel to theshaft A and has a rear threaded portion B; but the extreme rear endportion is left smooth, as shown at B A gear wheel B is carried by therod B, adapted to mesh with the gear A through the medium of anintermediate gear to be described hereinafter. Within the casing A is aframe C, adapted to travel along the rod B,

being suspended from the said rod, and the end member 0 of the frame inengagement with the threaded portion B of the rod B is threaded, andwhen the rod B is rotated the frame C is thereby advanced along the rod,the direction of travel of the frame depending on the direction ofrotation of the rod B. The frame C carries a chart G which travels withthe frame. On the lower horizontal member of the frame C is slidablysecured a hanger or stirrup G which is locked in its adjusted positionby a lock-nut actuated by a weighted handle 0". The hanger is providedwith a pointer C. The hanger is adapted to receive and support the freeend portions of pivoted blades D and D, spaced from each other in thehanger, and the hanger carries a depending guide-loop 0 adapted to guidethe signal-blade D as it falls. At its forward end the frame C carries apointer 0 adapted to travel along a fixed chart F.

The emergency-blade D and signal-blade D are pivoted in a hanger H,placed on the side of the casing A adjacent its forward end, the freeend of the blade D terminatingin advance of the free end of the blade D,and as the hanger moves rearwardly the signalblade D will fall first,being first deprived of i the support of the hanger C and in its fallwill be guided by the depending loop G which is suitably curved toconform to the arc described by the free end of the blade D. This bladehas a notch D formed adjacent its pivoted end, and the notch alines withan aperture D formed in the blade D. An aperture D is also formed in theblade D, which alines with an aperture D, formed in the blade D, and itwill be noted that the signalblade D extends in advance of the hanger Hand end of the casing A, being of greater length than the blade D. Apivot-pin D is passed loosely through the hanger H, which will bedescribed in detail hereinafter, and is non-rotatably secured in theaperture D of the blade D and passes loosely through the blade D at theaperture D serving as a pivotpin for the said blade D.

A vertical partition E is placed in the casing A immediately to the rearwith respect to the front of the casing of the rod B, and a pointer E isslidably carried by the upper edge of the partition E, this pointerbeing adapted to travel along the fixed chart F, heretofore mentioned,which chart is carried by the front face of the partition E.

While the casing A may be secured in the cab in any manner, I prefer toprovide it with a plurality of rings G, so that the casing may besuspended from a rod or pipe. (Not shown.)

The hanger H is in the form of a segment and is provided with angledslots H, intersected by the pivot-pin D and through these slots theblades D and D pass, the angling of the walls of the slots, as shown inFig. 8, permitting play of the blades on their pivotpoints: The curvededge or face of the hanger H is provided with two parallel grooves H inwhich rests coil-springs H secured at their lower ends to the hanger Hand at their upper ends to the blades D and D, respectively.

To the inner end of the pivot-pin D which, it will be remembered, isrigid with the blade D and which passes loosely through the signal-bladeD, is rigidly secured a curved arm J, to the free end of which ispivoted a link J, having its remaining end pivotally connected to an armJ rigidly connected in its turn to an emergency-valve J It will beobvious, therefore, that the fall of the emergencyblade D will throughthese connections actuate the valve J and that so far as the opera tionand construction of the parts heretofore I described are concerned it isimmaterial whether the valve J serves to cut off steam and bring theengine to a. stop or serves to set the air-brakes, and thus check thespeed of the train.

For illustrative purposes I have shown the connections whereby the fallof the emergency-blade D will open the train-pipe and permit the air toescape therefrom. From the valve J which is a three-way valve, a pipe Jextends to a cylinder J in which is a piston J 6 and a piston-rod J therod J reciprocating parallel to the train-pipe K, in which is placed aone-way valve K having a stem enlarged, as shown at K and "apertured. AU-shaped clip J is fastened to the pistonrod J and a link J is, pivotedin the clip and 'works freely through the aperture in the enlargedportion K of the stem of the valve K A coil-spring K returns the valveto its closed or normal position when the valve J is thrown to itsnormal position by the replacing of the blade D in the hanger Cpermitting air to es cape from the cylinder J To record the fall of thesignal-blade D, I provide a threeway valve 1, the stem of which isoperated by links I and I pivotally connecting the valvestem to theblade D, as shown in Figs. 1, 6, 7, and 8. This valve normally registerswith an exhaust-pipe 1 but on being actuated by the fall'of the blade Dcloses the exhaust and places a pipe 1, leading to an air-reservoir (notshown) in communication with a pipe L. The pipe L leads to a cylinder Lplaced vertically in a frame L, .and in the cylinder works a piston Lhaving a piston-rod L which at its upper end supports a cylinder L at aright angle tothe cylinder L A sheath L movable in the cylinder Lcarries a pencil L, held by a spring L in engagement with the back ofthe movable chart C The upper side of the cylinder L carriesverticalguide-rods L, working through apertures in a plate L andcoil-springs L, which encirclethe rods L", serve to hold the pencil inits normal horizontal plane.

In order that the apparatus may be reset after the carrier or frame Chas traveled its full limit on the rod B, I provide a handrotatedgear-wheel M at the forward end of IIO the casing A and a pivoted leverM, locked in locked by D is down, and it will be remembered that itsadjusted position by a set-screw M The lever carries a gear M meshing inallpositions of the lever with the gear-wheel B and in the normalposition of the lever with the gearwheel A By shifting the lever thegearwheel M and rotation of the said wheel by hand will rotate thegear-wheel B and the rod B, thus returning the frame C to itsstarting-point.

The ends of the frame 0 are detachable from the lower horizontal -memberof the frame, and the front end or non-threaded end member is locked inplace with a set-screw N, as shown most clearly in Fig. 13, thuspermitting ready removal of one chart and the substitution of another.

To prevent the fall of the emergency-blade after the signal-blade hasbeen dropped and the signal heeded by the engineer, a pipe 0 isconnected with a suitable air-reservoir and contains a valve actuated bya handle 0 is within reach of the engineer. By opening this valve air isadmitted into a cylinder 0 in which works a piston-rod O which serves asa lock-pin and enters the aperture D in the blade D, passing through thenotch D in the signalblade,' but it will be obvious that when thesignal-blade D is in its normal position supported by the hanger O thatthe locking-pin O is prevented from passing the blade D, and the blade Dcan therefore be the engineer only when the blade the fall of thesignal-blade will leave a pencil record on the back of the chart showingsuch fall. The locking-pin O carries a springcatch 0, which engages theupper edge of the hanger H when the blade D is locked and preventsreturn of the pin to its normal position until after the catch isdisengaged, which can be readily done with the thumb. A spring 0 willthen return the =pin*O to its normal position and unlock theemergencyblade. The signal-blade D can then be re turned to its normalposition.

To give an audible signal on the fall of the blade D, I provide a gong Pand a bracket P, to which is pivoted a lever P. A clapper P is carriedby the lever P and movement of thelever is limited bya stop P An endportion of the lever is in the path of the free end of the signal-bladeD, and the guide C insures that the blade strikes the lever on its fall,thus actuating the clapper and sounding the gong.

The charts C and F are provided with scales representing miles andfractions of a mile and with the names of stations, sidings, &c. I haverepresented these latter in Fig. 1 and designated them a b c, &c., andfor con venience of illustration have shown them as being equidistantfrom each other. It will be noted that the scale of one chart is reversewith respect to that of the other.

is engaged with the gear-wheel M reached the free end of The operationof the device is as follows: Assuming that the engineer has orders totake a siding at a certain point as beyond f, the hanger C is set at thepoint 00 on chart 0 and locked in such position by the lock C The chart0 is then brought into proper position by the engineer by rotation ofthe gearwheel Mthat is, assuming, again, that the engineer receives hisorders at c to take the siding at 00, he moves the chart C and frame Cuntil the pointer C registers with 0, his starting-point, 011 the fixedchart F. The gear-wheel M is then locked in engagement with thegear-wheel A and the rotation of the rod B will cause the chart totravel along the same and the pointer C along the chart F in thedirection of 0c. WVhen the pointer C? reaches :0, which may be taken asindicating not the siding itself, but a point on the road in advance ofthe siding where the signal is to be sounded, the hanger C will have thesignal-blade D and passing from under the same will permit it to fall,and the fall of the blade will sound the gong by reason of the bladestriking the lever P The fall of the blade will also through the valve Iadmit air into the cylinder L through the pipe L, and the piston L willmove upward, carrying the pencil L with it, thus breaking the straightline made on the back of the chart from c to ac. On hearing the alarmthe engineer can prevent the fall of the emergency-blade by moving thevalve-handle, O and admitting air into the cylinder 0 forcing the pin 0through the notch D of the blade D, which notch is brought intoalinement with the pin by fall of the blade, and the pin entering theaperture D will lock the blade D and prevent its falling when the hangerC has been carried beyond it. The engineer can then bring the train to astop to take the siding and can reset the device. It will be noted thatduring the time between the fall of the signalblade D and the stoppageof the engine the pencil L is held above its normal position and ismaking a record on the back of the chart which will show the exactdistance run by the engine from the time the blade D fell to the timethe engine came to a standstill, as the length of any line drawn by thepencil on the chart will be in a definite proportion to the distancetraveled by the engine while such line was being made without regard tothe speed of the engine, as the controlling factor is the number ofrevolutions made by the axle of the engine with which the gearing isconnected and as a matter of course the diameter of the wheels on suchaxle.

Should the engineer for any reason fail to hear or heed the signal, theemergency-blade D will fall after a predetermined distance has been run,such distance being fixed by the lead or extra length given the blade D,and the emergency-valve J will be thereby shown, nor are opened and thebrakes applied or the steam cut off, according as the said valve may beconnected to the air-brake system or the throttle-valve.

When the blades are reset, the parts are returned to their normalpositions, including the pencil L, the lifting of the blade permittingthe air in the cylinder L to exhaust through the pipe I and the springsL aiding in returning the cylinder L to its normal position.

To avoid any confusion in the drawings, no parts of the air-brake systemproper are the throttle-valve or parts of the engine itself shown, asnone of these are of my invention.
